Scope: This standard specifies the classification, raw materials, structural requirements, requirements, test methods, inspection rules, marking, packaging, transportation and storage of reinforced concrete well pipes (hereinafter referred to as well pipes). This standard applies to reinforced concrete well pipes made by centrifugal, suspended roller or other forming processes for water supply and drainage pipe wells. The hydrogeological environment and application environment where the tube well is located should have no corrosive effect on the reinforced concrete well pipe. When the working environment is corrosive to the reinforced concrete well pipe, protective measures should be taken before use.
